COUPLING GAS-MOTORS AND GAS -PRODUCERS.

SPECIFICATION forming part of Letters Patent N 0. 638,655, dated December 5, 1899.

Application filed February 1, 1899. Serial No, 704,135. No model) To (tZZ whom it; may concern:

Be it known that I, MAURIoE TAYLOR, a subject of Her Majesty the Queen of England, residing at Paris, France, have invented certain new and useful Improvements in Coupling Gas-Motors and Gas-Producers, of which the following is a specification.

Four-phase cycle-en gin es are recognized as being more advantageous than other gasmotors, as they, among other advantages, are economical of fuel, their cost is small, and they occupy but a small space. On the other hand, gas-producers generating poor gases which operate below atmospheric pressure are in every respect superior to gas-producers operating under pressure, being more simple and safer, in addition to which they may be cleansed while in operation and require no gasometer; also, the composition of the gases is uniform, whereby regularity in the operation of the engine is insured.

Hitherto it has been impossible to couple a four-phase cycle gas-engine with a gas-producer from which the gases are drawn by the engine, as the operating-piston employed in drawing in the gas has to draw in at the same time the air necessary for the combustion-of such gases. The composition of the explosive mixture is a matter that requires careful attention, even where both the gas and air are under a constant pressure; but where the pressure of the air only is constant, while the pressure of the gas varies, owing to the varying resistances it encounters on its way to, through, and from the gas-producer, the composition of the mixture of air and gas constantly varies and prevents the proper operation of the engine.

The chief object of my invention is to provide new and improved means for avoiding the objections referred to and causing the working piston to draw gas from a gas-producer and air from an air-reservoir, the air in the reservoir being constantly maintained at a less pressure than that of the gas. This object is accomplished in the manner and by the mechanism hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 isa diagratnmatical view showing the relation of the gas-engine, the gas-producer, the air-reservoir, the air cook or valve,

and the expansible and contractible case or bellows through which the piston draws the gas and which controls the air-cock; and Fig. 2 is a detail sectional view, omitting the gasproducer and the gas-engine.

In order to enable those skilled in the art to make and use my invention, I will now describe the'same in detail, referring to the drawings, wherein- The letter CL indicates an air chamber or reservoir having a pipe connection b with the air-suction valve (not necessary to show) of a gas-motor engine a The air chamber or reservoir a is provided with an air-inlet cock 0, which can be opened more or less by means of a lever cl, controlled by alinl; e and by a flexible case f, constructed to be expanded andcontracted and com posed, as shown, of a bellows or bag, one side, 9, of which is fixed, while the other, h, is movable. A pipe 1', leading from the gas-producer, opens into the said bellows f, while anothor pipe It; connects the said bellows with the gas-inlet valve of the motor-engine.

A counterweight 121 is provided for the purpose of maintaining the bellowsf expanded and the cock 0 fully open when the engine is in normal operation and the minimum resistance is ofiered to the gas drawn through the pipe 2' front the gas-producer t.

The lever d, hereinbefore referred to, is connected to the air-cock c, which turns with slight friction, so that it may follow the oscillating movements of the lever, the size of the orifice or port of the said cock being such that when the motor is in normal operation, the bellowsf being elongated to the full ext-ent and the cock 0 full on, the said cock still sufficiently contracts or throttles the air-inlet of the chamber a to reduce the pressure of the air contained in such chamber a to a degree somewhat below that of the pressure ex isting in the bellows f, all this taking place when the gas meets with a minimum resistance on its way from the gas-producer t" and purifying-chambers. The motor being thus in normal operation and the bellows f and the air chamber or reservoir to having been properly regulated, air and gas in suitable proportions are drawn in by the Working piston of the motor, they being proportioned by their respective inlets admitting them into the mo tor by means, for instance, of cocks such as are commonly used, the proportions in the several positions of the piston being the same as would prevail were the piston to draw in compressed gas, and air at the atmospheric pressure will when drawn in attain a pressure somewhat in excess of that of the air contained in the reservoir a. This will be the condition as long as the resistances in the gasproducer do not increase; but when they do increase the pressure in the gas-passages and bellows will diminish and the said bellowsf will collapse, its movable side It coming nearer to its rigid side g. During this movement of the bellows f the cock 0, through the agency of the link e and lever cl, before described, will close in proportion to the contraction of the bellows f, so that the pressure in the airchamber a will be maintained below the pressure of the gases. The gases and air will therefore in this case also enter the enginecylinder in the same proportions and the operation of the engine will proceed without undergoing any alteration by reason of any difference in the pressure of the gases drawn in.

Having thus described my invention, I claim 1. The combination of a gas-producer, an air-reservoir, a gas-engine,the piston of which draws in gas and air, and means for automatically maintaining the air-pressure in the air-reservoir less than the pressure of the gas drawn in, substantially as described.

2. The combination of a gas-engine, a gas producer, an air-reservoir having an air-inlet cook, a flexible expansible and contractible case operatively connected with the air-inlet cock, a conduit leading from the air-reservoir to the engine, a conduit connecting the gasproducer with the flexible case, and a conduit connecting the latter with the engines, substantially as described.

3. The combination of a gas-producer,a gas engine, an expansible and contractible case, conduit-s leading from said case to the gasproducer and engine, an air-reservoir connected with the engine and having an aircock, a lever connected with the air-cock, a link connecting the lever with the flexible case, and means for normally expanding the case, substantially as described.

4. The combination of a gas-engine gasproducer, an air-reservoir having an air-cock and connected with the engine, an expansiblc and contractible case connected with the gas producer and engine,and connections between i MAURICE TAYLOR.
